The Appointments Clause of Article II, Section 2, Clause 2, of the United States Constitution empowers the President of the United States to nominate and, with the advice and consent (confirmation) of the United States Senate, appoint public officials. Although the Senate must confirm certain principal officers (including ambassadors, Cabinet secretaries, and federal judges), Congress may by law invest the appointment of "inferior" officers to the President alone, or the courts of law, or the heads of departments.
